  \' A9 H( L# I. h( L9 u 请大家帮忙理解下面IEC60598-1 Section 9 标准中的要求。

For tests of 9.2.3 to 9.2.9, a fixed luminaire intended for mounting with its body in contact with
a surface shall be tested with an expanded metal spacer interposed between the luminaire and
the mounting surface. The spacer shall be at least equal in overall size to the projection of the
( B/ b% j6 K& _) ^luminaire, and have dimensions as follows:
Longway of mesh 10 mm to 20 mm
2 H2 R5 p7 k6 {& Z3 {Shortway of mesh 4 mm to 7 mm
Strand width 1,5 mm to 2 mm
Strand thickness 0,3 mm to 0,5 mm
" ]% @3 n( h. x7 IOverall thickness 1,8 mm to 3 mm

我的问题是：做IPX3和IPX4测试时，当灯具本身的安装面尺寸仅有100mm,但是灯具总的投影面有850mm。那么隔板的尺寸要需要多大呢？是刚好100mm或者是850mm.(注：隔板是用在灯具和安装面之间，做隔离。) 麻烦各位前辈帮忙解答这个问题。谢谢！
